A cab-control coach has an operators cab at one end. This car would be at the opposite end of the train from the locomotive and the cab enables the train to run “backwards” with the cab-control coach leading and the locomotive pushing. In practice, this eliminates the need to turn the entire train around at the end of a run. A “coach” does not have the cab and makes up the rest of the train.
Athearn makes the F59PHI locomotive in paint schemes to match the Bombardier cars. In actual service, these cars have been or are also pulled by EMD GP40TC’s, F40PH’s and F59PH’s as well as MPI’s MP36. I suggest you go to www.railpictures.net and check out appropriate photos.
